A community health nurse provides a flu prevention workshop at a senior center. Which theory of aging underpins these activities?
- A. Free radical theory
- B. Immunologic theory
- C. Oxidative stress theory
- D. Telomere theory
Correct Answer: B
Rationale: The correct answer is B: Immunologic theory. This theory of aging focuses on the decline in immune function as individuals age, making them more vulnerable to infections like the flu. The flu prevention workshop at the senior center aligns with this theory by aiming to boost seniors' immune systems to reduce their susceptibility to the flu.
A: Free radical theory attributes aging to the accumulation of damage caused by reactive oxygen species, not specifically related to immune function.
C: Oxidative stress theory is similar to the free radical theory in emphasizing the role of oxidative damage in aging, not directly related to immune function.
D: Telomere theory suggests that cellular aging is influenced by the shortening of telomeres, which is not directly related to immune function or flu prevention.

Which of the following assessment findings would be most suggestive of deep vein thrombosis (DVT)?
- A. Bilateral calf tenderness after walking up a flight of stairs
- B. Swelling in one leg with pitting edema
- C. Shortness of breath after activity
- D. Two plus palpable pulses
Correct Answer: B
Rationale: The correct answer is B because swelling in one leg with pitting edema is a classic sign of DVT. Pitting edema suggests fluid accumulation due to compromised venous circulation, which is common in DVT. Bilateral calf tenderness (choice A) is more indicative of muscle strain. Shortness of breath (choice C) is suggestive of a pulmonary embolism, a complication of DVT. Two plus palpable pulses (choice D) indicate good arterial circulation, not DVT.
A paper on culture and illness would likely include the statement that
- A. Culture is the same as ethnicity.
- B. Ethnic groups always share common geographic origin and religion.
- C. Ethnicity involves recognized traditions, symbols, and literature.
- D. Most members of an ethnic group exhibit identical cultural traits.
Correct Answer: C
Rationale: The correct answer is C because ethnicity involves recognized traditions, symbols, and literature. This statement aligns with the topic of culture and illness, as ethnicity plays a significant role in shaping cultural beliefs and practices related to health and illness. It highlights the importance of cultural elements in understanding how different ethnic groups perceive and address health issues.
A: Culture is not the same as ethnicity; culture encompasses a broader range of beliefs and practices.
B: This choice is incorrect as ethnic groups can have diverse origins and religions.
D: Most members of an ethnic group do not exhibit identical cultural traits as cultural diversity exists within ethnic groups.
On which biological theory of aging is the prevention of telomere shortening based?
- A. Genetic research
- B. Caloric restriction
- C. Oxidative stress
- D. Cross-link
Correct Answer: A
Rationale: The correct answer is A: Genetic research. Telomere shortening is primarily based on the theory of cellular senescence, which is related to genetic research. Telomeres are protective caps at the end of chromosomes that shorten with each cell division. Genetic research has shown that telomere shortening is associated with aging and age-related diseases. Caloric restriction, oxidative stress, and cross-link theories of aging are not directly linked to telomere shortening. Caloric restriction focuses on extending lifespan by reducing calorie intake, oxidative stress theory suggests that aging is caused by cumulative damage from reactive oxygen species, and cross-link theory emphasizes the accumulation of non-reversible bonds between molecules as a cause of aging.
In geriatric nursing, which factor is most important in determining the effectiveness of rehabilitation after a stroke?
- A. Age of the patient
- B. Family support and involvement
- C. Number of medications prescribed
- D. Patient’s previous health conditions
Correct Answer: B
Rationale: The correct answer is B: Family support and involvement. This is crucial in determining the effectiveness of rehabilitation after a stroke because a supportive and involved family can provide emotional support, encouragement, and assistance with activities of daily living. This positively impacts the patient's motivation, compliance with treatment, and overall well-being, leading to better rehabilitation outcomes.
A: Age of the patient - While age can be a factor in stroke recovery, it is not the most important factor as older patients can still make significant progress with proper rehabilitation and support.
C: Number of medications prescribed - While medication management is important in stroke recovery, it is not the most crucial factor for rehabilitation effectiveness.
D: Patient’s previous health conditions - While previous health conditions can impact stroke recovery, the level of family support and involvement plays a more significant role in determining the effectiveness of rehabilitation after a stroke.
What is the primary reason older adults with cognitive impairments experience difficulties with medication adherence?
- A. Lack of understanding of the importance of medication
- B. Cognitive decline affecting memory and decision-making
- C. Physical inability to manage medications
- D. Fear of side effects or drug interactions
Correct Answer: B
Rationale: The correct answer is B: Cognitive decline affecting memory and decision-making. Older adults with cognitive impairments, such as dementia, may struggle with remembering to take their medications as prescribed and making sound decisions regarding their medication regimen due to cognitive decline. Memory deficits can lead to missed doses, while impaired decision-making can result in improper adherence. Choices A, C, and D are incorrect as the primary reason for medication non-adherence in this population is the cognitive decline impacting memory and decision-making, rather than lack of understanding, physical inability, or fear of side effects.
